SETI Institute meteor astronomer Peter Jenniskens reports that Sunday night's fireball just west of the San Francisco Bay Area was captured by the CAMS camera networks in Sunnyvale (Jim Albers) and at Lick Observatory (Bryant Grigsby). The meteor first appeared at 8:18:20 pm local time on March 22, 2026. See the findings and add your report here: fireball.amsmeteors.org/members/imo_vi… #meteor #bayarea #science

Astronomers have discovered 11 more moons around Saturn, bringing its total to 285--by far the most of any planet in the solar system. The true number may be unknowable, if you count every ring particle as its own little moon. minorplanetcenter.net/mpec/K26/K26F1…

I Survived a Type Ia Supernova, and All I Got Was This Kick Velocity @Astrobites's Mckenzie Ferrari reports on an investigation of a runaway star that may have survived its companion going supernova. aasnova.org/2026/03/17/i-s…

🧵1/5 On 29 June 2025, the ASAS-SN detected a supernova in NGC 1637 at ≈ 39–40 Mly. One team searched old archive images & found the star that exploded: the first published detection of a supernova progenitor candidate by #JWST.

@victoranicio @volcaholic1 Olá. A Defesa Civil emitiu alerta para todo o Sul de Minas hoje de manhã.

@volcaholic1 My God, I’m from Minas Gerais and I had no idea what was happening in Ubá. 😱

Another video of the devastating flooding in the city of Ubá, in Minas Gerais, Brazil.... Time to wake up to climate change!

Did you know the lithium in your cell phone battery might have been created in a type of stellar explosion called a nova? A study suggests that the lithium found in our solar system and Milky Way comes from these cosmic events. go.nasa.gov/3OnRqNx #BatteryDay

Fireball spotted over Buenos Aires, Argentina last night...☄️

How Many Kilonovae Will Rubin Observatory Help Us Spot? The upcoming Vera C. Rubin Observatory Legacy Survey of Space and Time will detect an astonishing number of transients — including kilonovae from colliding neutron stars. aasnova.org/2026/02/04/how…

This year, YOU played a role in defending Earth 🌍 Diving into the 2025 discoveries made by the incredible @Unistellar community with the @SETIInstitute with our third highlight ! Citizen Science Highlight #3: Planetary Defense🌍 8 new main-belt shape models were created with the help of our data These main-belts were picked because they are relatively young (<10 million years) and dynamically fresh. The broader research goal is to study the link between asteroid fragmentation (which is what created these main-belts) and meteorites reaching Earth. To study this we need to know the same physical characteristics that go into determining the shape model through lightcurve inversion 22 flyby events were observed this year Davin Potts observed the full Eros lightcurve (4 hours) 5 times Top observer - Darren Rivett with 101 observations Target with most observations - Eros with 194 Total observations - 1603 Here's to another year discovering the universe with YOU 🥂 #citizenscience #year2025 #planethumans #Earth

F9/Starlink 17-19: SpaceX launched 25 more Starlink internet satellites from California this morning, the first of two planned Falcon 9 flights today; liftoff from pad 4E at Vandenberg SFB came as 12:53pm EST (1753 UTC); another Starlink flight, this one with 29 satellites, is scheduled for launch from Cape Canaveral at 11:01pm EST (0401 UTC)

The first 4 asteroids discovered this year are 2026 AA 2026 AB 2026 AC 2026 AD

ASASSN-26af in the LMC is not happy:

How will our upcoming Pioneer satellite Pandora help us learn about the atmospheres of worlds outside our solar system? By observing planets and stars simultaneously! It'll study stars' spotty surfaces to separate the signal of a planet from its host star: go.nasa.gov/4bhjyv2

EE Cephei is a long period eclipsing variable star (5,6 years). It’s a “disk-occulting system” with irregular eclipses caused by a star and a disc of gas & dust too. Here is the current V filter light curve obtained by R.Casas (red dots) & myself (blue dots, Anysllum observatory)

📬 “You’ve got data.” We're wrapping up #RubinRecap2025 with one more highlight: scientists (and you!) got access to some early NSF–DOE Rubin Observatory data! This year, Rubin: 🧵

🐣 Found: newborn stars and planets @ESAGaia and @almaobs joined forces to study 31 baby star systems, finding hints of planets 👉 esa.int/ESA_Multimedia… The collage also shows our own Solar System for reference on the bottom right, as it is predicted to have looked at an age of 1 million years.
